Generally speaking, the length of the contract signed between employers and employees is negotiated by employees and employers. The length of the labor contract is related to the length of the probation period. The probation period generally cannot exceed 6 months.

People's Republic of China (PRC) labor contract law

Article 19 If the term of a labor contract is more than three months but less than one year, the probation period shall not exceed one month; If the term of the labor contract is more than one year but less than three years, the probation period shall not exceed two months; The probation period of a labor contract with a fixed term of more than three years or without a fixed term shall not exceed six months.

The same employer and the same worker can only agree on a probation period.

A probation period may not be stipulated in a labor contract whose term is to complete certain tasks or whose term is less than three months.

The probation period is included in the labor contract. If the labor contract only stipulates the probation period, the probation period is not established, and this period is the term of the labor contract.
